• Because the ECOM’s PLCs have been configured to talk between themselves (i.e. ECOM-to-ECOM) using the RX/WX commands in the PLCs. • NetEdit software on a PC connected to the network sends out broadcasts to find Host Engineering Ethernet devices . . . ECOMs respond in like manner. • If an application of any kind on the PC connected to the network is sending broadcasts out, the ECOM will respond in like manner.
